New Hampshire became the ninth state to join the United States on June 21, 1788, by ratifying the U.S. Constitution. Located in New England, it played a key role in the American Revolution and was the first state to establish its own constitution independent of British rule. Known for its motto “Live Free or Die,” New Hampshire values independence and civic involvement. Its capital is Concord, and it is also famous for holding the nation’s first presidential primary during election seasons.
